行數據拆分但不拆分列標題

你好

 

我可以打開csv文件，而不會出現以下任何問題。如何讀入具有_和|的每列的第一個值分裂。我想保持列標題相同的名稱，以便以後進行繪製。

我試圖打開w / Data Preview以刪除_或|但它也會拆分列標題。

 

Data: <BR />ID,Name,Country,Column1_Value,Column2_Value_More,Percent_Name_Count<BR />125480,Jack,CA,0.310_0.310_0.310_0.310_0.310_0.310_0.310_0.310,0.610|0.610|0.610|0.610|0.610|0.610|0.610|0.610,0.7<BR /><BR />Keep: <BR />ID,Name,Country,Column1_Value,Column2_Value_More,Percent_Name_Count<BR />125480,Jack,CA,0.310,0.610,0.7

 

 

 

csv_file = "C:/test3.csv";
Open(csv_file);

不知道為什麼格式搞亂了。想要顯示數據中的內容以及我想要保留的內容。

 

Data: 
ID,Name,Country,Column1_Value,Column2_Value_More,Percent_Name_Count
125480,Jack,CA,0.310_0.310_0.310_0.310_0.310_0.310_0.310_0.310,0.610|0.610|0.610|0.610|0.610|0.610|0.610|0.610,0.7

Keep: 
ID,Name,Country,Column1_Value,Column2_Value_More,Percent_Name_Count
125480,Jack,CA,0.310,0.610,0.7

再次感謝。

這是使用Word（）函數的非常簡單的操作。  JMP具有一些非常強大的字符處理功能。  有關文檔，請參見《腳本指南》和《腳本索引》。

names default to here(1);
dt=open("c:\test3.csv");

For Each Row(
 :Column1_Value = word(1, :Column1_Value, "_" );
 :Column2_Value_More = word(1, :Column2_Value_More, "|" );
);

dt:Column1_Value << data type(numeric);
dt:Column1_Value << modeling type(continuous);
dt:Column2_Value_More << data type(numeric);
dt:Column2_Value_More << modeling type(continuous);

謝謝您的快速回复。如何避免對word（）的特定列使用硬編碼。我可以在Cols中使用for循環來動態更改_和|嗎？

 

謝謝。

1. 給定您要提出的問題，您需要花一些時間來學習JSL的基礎知識。  請花時間閱讀《腳本指南》：幫助==> JMP文檔庫==>《腳本指南》
2. 為了回答您的問題，我從原始腳本中修改了一個Word（）函數以使用動態引用

   names default to here(1);
   dt=open("c:\users\jim\documents\test3.csv");
   
   myWord = 1;
   myColumn = "Column1_Value";
   myDelimiter = "_";
   
   For Each Row(
    :Column1_Value = word(myWord, as Column( myColumn ), myDelimiter );
    :Column2_Value_More = word(1, :Column2_Value_More, "|" );
   );
   
   dt:Column1_Value << data type(numeric);
   dt:Column1_Value << modeling type(continuous);
   dt:Column2_Value_More << data type(numeric);
   dt:Column2_Value_More << modeling type(continuous);

很抱歉我是新來的人，正在學習JSL。 

如果我有更多的列標題，我不想對列標題名稱進行硬編碼，而是循環遍歷以獲得split _或|的第一個值。我嘗試在下面嘗試，但我知道我的代碼已損壞。

 

 

csv_file = "C:/test3.csv";
CSV_data = Open( csv_file ); 

col = CSV_data << get column names( string );
nc = N Items( col );

For( i = 1, i <= nc, i++, 
 For Each Row(
  :col[i] = Word( 1, col[i], "_" );
  :col[i] = Word( 1, col[i], "|" );
 );
);

非常接近，但是如果您查看我發送的最後一個代碼，您會看到在引用要執行的列時，我在其前面放置了一個As Column（），因此您實際需要的是

names default to here(1);

csv_file = "C:/test3.csv";
CSV_data = Open( csv_file ); 

col = CSV_data << get column names( string );
 
nc = N Items( col );

// You don't want the first 3 columns processed,
// or the last one processed, so the index values
// to be used needs to be changed to handle this
For( i = 4, i <= nc - 1, i++, 
 For Each Row(
  as column(col[i]) = Word( 1, as column( col[i]), "_|" );
 );
);
